For a smoother consistency, peel the carrots and apples thoroughly. Removing the skins helps create an extra-silky purée. Adjust the amount of breast milk or formula to reach your baby's preferred consistency. Some babies prefer a thicker purée, while others enjoy a thinner one. To retain more nutrients, consider steaming the carrots and apples instead of boiling. Steaming helps preserve vitamins and minerals. This purée can be made in larger batches and frozen in individual portions for later use. Be sure to use freezer-safe containers and label with the date. Always check the temperature of the baby food before feeding it to your baby to avoid burns.
